INSTRUCTIONS FOR CONTRIBUTORS

• Form and preparation of manuscripts

ATMOSFERA is dedicated to the publication of theoretical, empirical, and applied research on all aspects of the atmospheric science, including meteorology, climatology, aeronomy, atmospheric physics, chemistry, and biology. Interdisciplinary papers are also encouraged, particularly those related to oceanography, hidrology, ecology, forestry, glaciology, agriculture, and air pollution. Atmósfera publishes articles, short contributions and correspondence in English. Submission of a contribution is assumed to indicate that no similar paper, other than an abstract or preliminary report, has been or will be submitted for publication elsewhere. Short contributions should not exceed four pages. Correspondence is intended for discussion of papers published in the journal and should not exceed one page.

Manuscripts. Please submitt an electronic copy of final version of manuscript, preferably prepared with MS Word or other compatible software, to the following address: editorial@atmosfera.unam.mx. It should be formatted with wide margins, double-spacing and all pages numbered. Footnotes to the text should be avoided. When symbols in mathematical work could be in doubt, the authors should submitt a list identifying typographically the symbols used. Equations will be numbered in parentheses to the right.

Title, Name, Address. Provide the title in full, author's name, affiliation, e-mail and present postal address.

Abstract. All articles shall include an abstract, both in Spanish and in English. Abstracts are not required for short contributions.

Text . The text should be divided into sections, each with a separate heading.

Acknowledgements. Brief.

Appendix. Lengthy mathematical analyses whose details are subordinate to the main theme of the paper should normally appear in an appendix. Each appendix should have a title.

Units, abbreviations and symbols. The International System of Units (m, kg, s, K) should be used. Only standardized terms that have been generally accepted should be used. Unfamiliar abbreviations must be defined when first used. Particular care should be taken to ensure that all symbols are clearly identified. The minus sign should be –.

References. Articles should be fully documented with references in the text and a reference listing ordered alphabetically by author's names at the end of the paper. Authors are encouraged to adjust to citation system. Examples:

References cited in the text should indicate, within parenthesis, the last name of each author and the year of publication. If there is more than two authors, the last name of the first author should be followed by et al. When such name form part of the content of the article, and do not appear solely as a reference, the year of publication is parenthesized.

For example:

...a weekly cycle has been observed in surface temperature (Gordon, 1994).

...Gordon (1994) has observed a weekly cycle in surface temperature.

Illustrations and tables. Electronic files (preferably in tif, eps or jpg formats, with a minimum resolution of 300 dpi), photographs of good quality and contrast, and drawings printed on paper are accepted. Maps should preferably be oriented so that the meridian through the center of the drawing is parallel to the sides. Figure legends should be self-explanatory and printed on a separate sheet of paper. All figures should be numbered and specifically mentioned in the text by number. Please number all tables with Roman numerals and include a short title.

Proofs. Copies of the proofs will be sent to the author. Revised proofs should be returned to the publisher without delay. The only changes that could be accepted in proofs are on grammar or related to printing errors.

Offprints. Authors of articles will receive 10 offprints free of charge, additional ones must be paid for by the author. Request forms for offprints will be enclosed with the proofs.
